1 FCC Related Statements
Warning: Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his

2 Overview
The ZXSDR A8988S is an 8T8R AAU integrated with antenna, and its ultra wide
bandwidth and large capacity make it quite suitable for macro coverage in various
scenarios.
Generally, the existing distributed base stations use the BBU + RRU architecture. As an
AAU, the ZXSDR A8988S is connected with the Base Band Unit (BBU) by optical fibers
to form an integrated base station. It has internal antennas to provide the Uu interface to
the User Equipment (UE).
Figure 2-1 shows its position in the TD-LTE system.

5 System Structure
An aluminum-alloy die-casting chassis with plastic antenna housing is used for the ZXSDR
A8988S. The chassis has the traits of light weighted and excellent heat dissipation. With
AAS integrated design, the ZXSDR A8988S has the features of small size and compact
structure.
The following figure shows the external view of the ZXSDR A8988S.
Figure 5-1 External View of ZXSDR A8988S
The external interfaces of the chassis are distributed in the side operation maintenance
unit and in the bottom chassis. The side operation maintenance unit includes an
embedded DC power interface and two optical interfaces (OPT1 and OPT2). The
indicators and operation maintenance unit are located on the same side so that the
operational status of ZXSDR A8988S can be easily observed.
The following figure shows the side interfaces of the ZXSDR A8988S.
